I've seen this in Bjarne's C++11 FAQ/INFO pages,
but why would you do that? It's weird and uncommon.
Virtual implies functionality to be overridden.
If no override is permitted,
just use good-old plain member function.

struct A {
  void f();
};

struct B : A {
  void f();  // Comiler may warn about the hiding of A::f
};
